a system of linear equations is given by the tables. one of the tables is represented by the equation y=-1/3x+7. The equation that represents the other equation is y= x + the solution of the system is ( , )
Answer:
1). Other line is, y = [tex]\frac{1}{3}x+5[/tex]
2). Solution of the system is (3, 6)
Step-by-step explanation:
From the table (1),
Let the equation of the line from the given table is,
y - y' = m(x - x')
Where m = slope of the line
(x', y') is a point lying on the line.
Choose two points from the table which lie on the line.
Let the points are (0, 5) and (3, 6)
Slope = m = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
= [tex]\frac{5-6}{0-3}[/tex]
= [tex]\frac{1}{3}[/tex]
Therefore, equation of the will be,
y - 5 = [tex]\frac{1}{3}(x-0)[/tex]
y = [tex]\frac{1}{3}x+5[/tex] -------(1)
Let the other line from the table (2) is,
y - y" = m'(x - x")
Two points taken from this table are (0, 7) and (3, 6)
m' = [tex]\frac{7-6}{0-3}[/tex]
= [tex]-\frac{1}{3}[/tex]
Equation of the line will be,
y - 7 = [tex]-\frac{1}{3}(x-0)[/tex]
y = [tex]-\frac{1}{3}x+7[/tex] -------(2)
Therefore, equation of the other line will be, y = [tex]\frac{1}{3}x+5[/tex]
By adding equations (1) and (2),
y + y = [tex]-\frac{1}{3}x+\frac{1}{3}x+5+7[/tex]
2y = 12
y = 6
From equation (1),
6 = [tex]\frac{1}{3}x+5[/tex]
[tex]\frac{1}{3}x=7-6[/tex]
x = 3
Therefore, solution of the system is (3, 6).
Answer:
The first line is 1/3x and 5. For the second line the answer is (3,6).
What is the area of the composite figure? (6π + 4) cm2 (6π + 16) cm2 (12π + 4) cm2 (12π + 16) cm2
Answer:
16 + 6pi
Step-by-step explanation:
We have a square and 3 semicircles
The area of the square is
A = s^2 and the side length is 4
A = 4^2 = 16
The radius of the semi circle is 2
The area of a semicircle is
1/2 pi r^2
1/2 pi (2)^2 = 2pi
We have 3 of them
3 *2pi = 6pi
Add the areas together
16 + 6pi
Answer:
(6π + 16) cm²
Step-by-step explanation:
The composite shape can be cut into 4 shapes.
3 equal semi-circles and 1 square.
The square has a side length of 2 + 2 = 4cm.
The radius of the semi-circle is 2 cm.
The area of the square is:
4 × 4 = 16 cm²
The area of the semi-circle is:
2²π × 1/2
= (2π) cm²
There are 3 equal semi-circles, so multiply the area by 3.
2π × 3 = (6π) cm²
Add the areas of the 4 shapes.
16 cm² + (6π) cm²
= (6π + 16) cm²
The total area of the composite shape is (6π + 16) cm².
The probability that your ticket will be chosen is 6%. There are 250 tickets in the drawing. How many tickets are yours?
Answer: 15
Step-by-step explanation:
6 percent of 250 is 15
15/250 = 6%.
Answer:
6% = 6/100 = 0.06
250 x 0.06 = 250 x 6 / 100
250 x 6 = 1500 / 100 = 15
15 tickets are mine

Initially, there were only 86 weeds in the garden. The weeds grew at a rate of 18% each week. The following function represents the weekly weed growth: f(x) = 86(1.18)x. Rewrite the function to show how quickly the weeds grow each day. f(x) = 86(1.02)x; grows approximately at a rate of 0.2% daily f(x) = 86(1.18)7x; grows approximately at a rate of 1.8% daily f(x) = 86(1.02)7x; grows approximately at a rate of 2% daily f(x) = 86(1.187)x; grows approximately at a rate of 0.18% daily
Answer:
Correct option: third one
f(x) = 86(1.02)7x; grows approximately at a rate of 2% daily
Step-by-step explanation:
We can rewrite the equation using the model:
P = Po * (1 + r/n) ^ (nt)
Where P is the final value, Po is the inicial value, r is the rate, t is the time and n is the relation of the rate and the time (in our case, the rate is weekly and the time will be in days, so n = 7)
With P = f(x), Po = 86, r = 0.18 and t = x, we have:
f(x) = 86 * (1 + 0.18/7) ^ (7x)
f(x) = 86 * (1.02) ^ (7x)
So the daily rate of growth is approximately 2%
Correct option: third one

What is the range of the functuon f(x)=(x-4)(x-2)
Answer:
The range is [-1, ∞).
Step-by-step explanation:
The points where the graph of this function cut the x axis are at x = 2 and x = 4 , it opens upwards and has a minimum value.
It has a minimum value when x = (2 + 4) / 2 = 3.
When x = 3, f(x) = (3 - 4)(3 - 2) = -1.
So the range is all real values of x >= -1, or [-1, ∞)

Pat's Potato farm grew 490 ponds of potatoes. Pat delivered 3/7 of the potatoes to the vegi stand. The owner of the vegi stand delivered 2/3 of the potatoes he bought to the grocery store,witched packedged half of the potatoes that were delivered into 5 pound bags. How many 5 pound bags did the grocery store package?
Answer:
Step-by-step explanation:
Pat's Potato farm grew 490 pounds of potatoes. If Pat delivered 3/7 of the potatoes to the vegi stand, it means that the number of pounds of potatoes that pat delivered to the vergi store is
3/7 × 490 = 210 pounds
The owner of the vegi stand delivered 2/3 of the potatoes he bought to the grocery store. It means that the amount delivered to the grocery store is
2/3 × 210 = 140
If half of the delivered potatoes was packaged in bags of 5 pounds each, it means that the amount of potatoes packaged in the bags is 140/2 = 70 pounds.
The number of bags of 5 pounds that the grocery store packaged is
70/5 = 14 bags

1. The budget above was created by Alex to help him plan how he will spend the money she earns. He usually earns
$20 each week by babysitting and running errands for his parents. If Alex is sick one weekend and can't earn the
$20. how much will he earn for that 4-week period (assume there are 4 weekends in the month)?
Answer:
Alex will be able to earn $60 for that 4-week period.
Step-by-step explanation:
It is given that
Income to Alex each week by babysitting and running errands:
$20.
To find the 4-week period earning, we need to add the value $20 for 4 times:
20 + 20 + 20 + 20 = $80
OR
In other words, 4 week period earning = 4 [tex]\times[/tex] 20 = $80
But, Alex was sick at one of the weekends, so $20 would be earned less.
Hence, during that 4-week period, total earning = $80 - $20
[tex]\Rightarrow[/tex] $60
So, Alex will be able to earn $60 for that 4-week period.
The probability that a foot ball team will win a game is 2/11.The probability that they will lose is 3/11.What is the probability the game will be a draw
Answer:
6/11
Step-by-step explanation:
Since there are 3 possible outcomes for the game (win,lose and draw) and the total probability for the three outcomes must be equal to 1.
Then;
The probability that the game will be a draw Pd = 1 - (probability that they will lose Pl + probability that they will win Pw)
Pd = 1 - (Pl + Pw) ........1
Given;
Pl = 3/11
Pw = 2/11
Substituting the values into equation 1;
Pd = 1 - (2/11 + 3/11)
Pd = 6/11
The probability that the game will be a draw Pd = 6/11

If a number is increased by 28 and then divided by 5, the result is 7.
The algebraic equation is
x + 28 divided by 5 =7.
what is x
x+28 / 5 = 7
Multiply both sides by 5:
x +28 = 35
Subtract 28 from both sides:
x = 7
